## Background
FIELD OF THE INVENTION
This invention relates generally to universal serial bus ports, and relates more particularly to hubs incorporating multiple universal serial bus ports.
BACKGROUND OF THE INVENTION
Universal serial bus technology has provided computer users with enhanced connectivity capabilities between computers and an increasingly wider range of peripheral devices. Universal serial bus hubs incorporating multiple universal serial bus ports into a single housing offer the ability to connect multiple peripheral devices to each other or to a computer via a universal serial bus connection. Some existing universal serial bus hubs are stackable. Although connecting a peripheral device using a universal serial bus hub can be as easy as simply plugging a universal serial bus cable into a universal serial bus port, existing universal serial bus hubs tend to place their ports in places that can be difficult to access. Additionally, existing universal serial bus hubs do not lend themselves to good cable management, leading instead to unsightly and inefficient cable arrangement. Accordingly, a need exists for a universal serial bus hub capable of being oriented in a direction chosen by the user. A further need exists for a universal serial bus hub configured to allow cables to exit from the universal serial bus hub in any direction, or in a single direction.

DETAILED DESCRIPTION OF THE DRAWINGS
In one embodiment of the invention, a universal serial bus hub includes a housing, a power port, a first universal serial bus port, and a second universal serial bus port. The housing includes a middle portion, a top portion coupled to the middle portion, and a bottom portion coupled to the middle portion opposite the top portion. The middle portion has a first region, a second region substantially opposite the first region, and a third region, where the third region is between the first region and the second region. The power port is located at the first region, the first universal serial bus port is located at the second region, and the second universal serial bus port is located at the third region.
FIG. 1 is a perspective view of a universal serial bus hub 100 according to an embodiment of the invention. FIG. 2 is a side view of universal serial bus hub 100 according to an embodiment of the invention. Referring to FIGS. 1 and 2, universal serial bus hub 100 comprises a housing 110, a power port 210, a universal serial bus port 120, a universal serial bus port 220, and a foot 240. Housing 110 comprises a middle portion 112, a top portion 111 coupled to middle portion 111, and a bottom portion 113 coupled to middle portion 112 and opposite top portion 111. In one embodiment, at least a portion of housing 110 is coated with a rubberized material. Top portion 111 comprises a portion 151. Middle portion 112 comprises a region 161, a region 162, a region 163, and a recess 118. In one embodiment, regions 161, 162, and 163 are in recess 118. Power port 210 is at region 163, universal serial bus port 120 is at region 161, and universal serial bus port 220 is at region 162.
In one embodiment, universal serial bus port 120 comprises an upstream universal serial bus port, meaning universal serial bus port 120 is configured to receive one end of a universal serial bus cable whose other end is attached to a computer. As an example, universal serial bus port 120 can be a mini B universal serial bus port. In the same or another embodiment, universal serial bus port 220 is one of a group of downstream universal serial bus ports. In one embodiment, the group of downstream universal serial bus ports consists of four downstream universal serial bus ports.
Universal serial bus 100 can be oriented in any configuration with respect to the computer to which it is attached. Furthermore, each of universal serial bus port 120 and power port 210 can be used with cables having right angle plugs. Accordingly, each of the cables attached to universal serial bus hub 100 can be guided away from universal serial bus hub 100 in a single direction, if desired, thus increasing aesthetic value of the work space as well as increasing efficiency in terms of the amount of work space used.
As an example, consider a case where a user chooses to orient universal serial bus hub 100 such that region 162 faces away from the user. Right angle plugs on the cables used with universal serial bus port 120 and power port 210 can then be rotated such that the cables exit both universal serial bus port 120 and power port 210 in a direction away from the user, as would the cables coming from universal serial bus port 220. Alternatively, consider a case where a user chooses to orient universal serial bus hub 100 such that region 162 faces the user. Right angle plugs on the cables used with universal serial bus port 120 and power port 210 can then be rotated such that the cables exit both universal serial bus port 120 and power port 210 in a direction toward the user, as would the cables coming from universal serial bus port 220. In both such cases, universal serial bus hub 100 lends itself to advantageous cable management in that all of the cables exiting the universal serial bus ports and the power port of universal serial bus hub 100 can be arranged such that they are all oriented in a single direction.
In one embodiment, portion 151 of top portion 111 comprises a translucent material. In the same or another embodiment, universal serial bus hub 100 further comprises a status indicator 130 at top portion 111. Status indicator 130 indicates a status of at least one of power port 210, universal serial bus port 120, or universal serial bus port 220. As an example, status indicator 130 can light up to indicate that adequate power is being provided to universal serial bus hub 100, that one or more of power port 210, universal serial bus port 120, or universal serial bus port 220 are functioning properly, and/or the like. As a further example, status indicator 130 can be a light emitting diode. In one embodiment, status indicator 130 is visible through portion 151 or the translucent material. In the same or another embodiment, status indicator 130 is one of a group of status indicators. As an example, each one of the group of status indicators can indicate a status of one of the group of downstream ports.
